Hi,

In LM5146, Web page, i could see the Output Current Max mentioned as 30A. How can Controller IC has Power stage Output current limitation ? Does it mean that i cannot use it for > 30A ?

Thanks,
Sandeep.

Hello Sandeep,

You can with careful design considerations and with thermal management. I encourage you to use the calculator, link below.

LM5146DESIGN-CALC Calculation tool | TI.com

Ultimately, it will come does to component selection. We would typically advise using an interleaved approach, please consider the LM5143.

Hope this helps.
